To all whom it concern:- 7 Be it known that I,'MA1rrrN- VAN MARLE,- a

subject of the-King of Great Britain, resid In my said ;prior invention I employ on a goods carr age longitudinally disposed goods carrying bars comblned'with means for raising and lowering such bars on said goods carriage for the purposeof "feeding goods into and removing goods from annealing and other furnaces. Mypresent invention comprises improved means forjim parting endwise movements to the goods carrying bars on the goods carrlagefand im' proved means for so su'pporting the goods carrying bars on the carriage that the longitudinal movement of the goods carrying barsin the one or the other direction causes the goods'carr the carriage,

' According to my present inventioIiI employ at certain intervals apart on the carriage (or on the goods carrying bars) inclinedblocks ying bars to rise or fall on combined with rollers'on the goods'carrying bars (or on the carriage)"the inclined surfaces of the saidblocks terminating in substantially horizontal parts so that as the goods carrying bars'are moved endwise in one direction the rollerson the "goods carrying bars roll up the inclined blocks on the carriage, thereby'raising the goods carrying bars until thelroller's arrive on'thetop fiat faces of the inclines, or the inclinedblocks on the goods ca'rrying bars n1ove along the rollers on the goods carriage until thefflat end lower parts o'f'the'in c'lines arrive on the tops of the rollers, and thus the goods carrying bars and the goods thereon are raised. The-goods carrying bars are combined with suitable means for moving them longitudinally in one or the other direction. Thus, by employing the said combined rollers and omrscmmme tamens.-

inclined blocks, the and-the risirig and lowering of th'e' goodscarryin'g bars is facilitated 'and-when the rollers arrive at the horizontalparts of the inclines as when the goods carrying bars are in their highest position there is notendency: for the ,goodscarryingbars to run back.

'Anothenpart of my'invention relates to an improved means for-imparting endwise movement to thego'ods carrying bars] Accordingto this part of myinvention' I provide a transverse shaft on the carriage and a pair-'ofeccentrics: or their equivalents on this shaft and eccentricrods-or their equivalents connecting the eccentrics or the like one with each-bar,means-also being pro.-

vided' forgiving a rotary motion to the transverse shaft. i

Referring' to the drawings I Figure 1 is a view in side elevationpartly Y in sectionshewingthe improved means for raising. bars. U a i v F igure 21s a view'in side elevation partly and f lowering the goods carrying in section shewing the' goods carrying bars 1 in their upper position. Figure3 is a plan,view-.--

Figure4-is anend view. 7 i Figure 5 is an end view taken from the opposite end to-that-shewn in Figure 4:.

eral arrangement of the machine is similar to that descr bed. in: m prior patent referred to, there'being anzundercarrlageyl mounted upon wheels'Q which run on rails 3, it being understood that the rails?) are parallel to'th'e'row of furnace doors. 1 v The undercarriage 1 servesas a support for a travelling carriage'which maybedesignateol asa vvhole'l l This travelling carriage ,4 comprises a lower member 5 having rollers 6 bywhic'hthe travelling carriag'e can move along guides upon the-"undercarriage 1. 4

, Themember' 5 is provided withajsuitable numbenof inclines'7, the upperends of which. terminate in horizontal surfacesjS;

" The upper members '9 ;0f 'the travelling carriage, constitute the goods carrying bars and thesemembers 9 are provided with a number of rollers which col-operate with the inclines 7 andthe surfaces 8, the movement being such that'when the members 9 are moved in an endwise direction relatively to the member 5 the members 9 are either raised orlowered.

In the'construction illustrated the gen- As in the machine described in my prior patent referred to, the carriage 4 can as a whole be moved in an endwise direction by gearing which includes a chain 11 passing over a pulley 12 driven by gearing 13 operated by a handle 14 or in any other suitable manner. Y

In order to simplify the,-mechanism for imparting the necessary longitudinal movements totlie goods carrying bars 9 when raising or loweringthe same, the goods carrying bars 9 are connected by two, eccentric rods or the like 15 on to two eccentricslG or dislike on a cross shaft 17 carried by the goods carriage 4 and on this shaft 17 there is a worm wheel 18 gearing with a worm 19 mounted so that it is caused to turn with but allowed to slide along a longitudinal square or other shaft 20 at the side of the carriage furnishedwith turning means 21 at its back end so that by turning this shaft and the worm and worm wheel gearing therewith and eccentrics the necessary longitudinal movement in the one or the other direction will throughthe eccentric rods or the like be imparted to the goods carrying bars which at or near their back ends are tied together at 22 asare the side bars of the carriage 5 but at the front ends the side bars of the carriage ass between guide rollers 23 mounted on rackets on the undercarriage, these guide rollers 23 thus preventing lateral displacement of the side bars 5 of the carriage as it goes into or out of the furnace,

lVhat I claim then is y 1. Apparatus for feeding goodsinto or removing goods from furnaces, comprising an undercarriage,-an upper travelling carriage inovably mounted thereon, said upper carriage including a supporting element and an independent goods carrying element resting thereon, inclinedblocks on one of said elements having each an inclined face and a substantially horizontal face, abutments on the other of said elements, means carried by said undercarriage for moving saidupper travelling carriage as a whole with respect to the undercarriage and means carried by said upperv travelling carriage for moving one of. said elements with respect to the other of said elements irrespective of movement of the undercarriage, whereby said inclined blocks co-act with saidabutments to alter the level of the goods carrying element.

2. Apparatus for feeding goods into or removing goods from furnaces, comprising an undercarriage, anupper travelling carr ia 'e movably mounted thereon, said upper o n carriage including a supporting element and an independent goods carrying element resting thereon, inclined blocks on one ,riage movably' mounted thereon,

of said elements havin each an inclined face and a substantial y horizontal face,

abutments on the other of said elements, means carried by said undercarriage for moving said upper travelling carriage as a whole with respect to the undercarriage, means carried by said upper travelling carriage for moving one of said elements with respect to the other of said elements irrespective of movement of the undercarriage, and means, carried by said undercarriage for operating. the means for moving one of the uppertravelling elements whereby said inclined blocks co-act with said abutments to alterthe levelo-fthe goods carrying element. 1 g
